+Node.js body parsing middleware.
+
+This does not handle multipart bodies, due to their complex and typically large nature. For multipart bodies, you may be interested in the following modules:
+
+- [busboy](https://www.npmjs.org/package/busboy#readme) and [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
+- [multiparty](https://www.npmjs.org/package/multiparty#readme) and [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
+- [formidable](https://www.npmjs.org/package/formidable#readme)
+- [multer](https://www.npmjs.org/package/multer#readme)
+
+Other body parsers you might be interested in:
+
+- [body](https://www.npmjs.org/package/body#readme)
+- [co-body](https://www.npmjs.org/package/co-body#readme)
+
+## Installation
+
+```sh
+$ npm install body-parser
+```
+
+## API
+
+```js
+var bodyParser = require('body-parser')
+```
+
+### bodyParser.json(options)
+
+Returns middleware that only parses `json`. This parser accepts any Unicode encoding of the body and supports automatic inflation of `gzip` and `deflate` encodings.
+
+The options are:
+
+- `strict` - only parse objects and arrays. (default: `true`)
+- `inflate` - if deflated bodies will be inflated. (default: `true`)
+- `limit` - maximum request body size. (default: `<100kb>`)
+- `reviver` - passed to `JSON.parse()`
+- `type` - request content-type to parse (default: `json`)
+- `verify` - function to verify body content
+
+The `type` argument is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) library. This can be an extension name (like `json`), a mime type (like `application/json`), or a mime time with a wildcard (like `*/json`).
+
+The `verify` argument, if supplied, is called as `verify(req, res, buf, encoding)`, where `buf` is a `Buffer` of the raw request body and `encoding` is the encoding of the request. The parsing can be aborted by throwing an error.
+
+The `reviver` argument is passed directly to `JSON.parse` as the second argument. You can find more information on this argument [in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
+
+### bodyParser.raw(options)
+
+Returns middleware that parses all bodies as a `Buffer`. This parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+The options are:
+
+- `inflate` - if deflated bodies will be inflated. (default: `true`)
+- `limit` - maximum request body size. (default: `<100kb>`)
+- `type` - request content-type to parse (default: `application/octet-stream`)
+- `verify` - function to verify body content
+
+The `type` argument is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) library. This can be an extension name (like `bin`), a mime type (like `application/octet-stream`), or a mime time with a wildcard (like `application/*`).
+
+The `verify` argument, if supplied, is called as `verify(req, res, buf, encoding)`, where `buf` is a `Buffer` of the raw request body and `encoding` is the encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.text(options)
+
+Returns middleware that parses all bodies as a string. This parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+The options are:
+
+- `defaultCharset` - the default charset to parse as, if not specified in content-type. (default: `utf-8`)
+- `inflate` - if deflated bodies will be inflated. (default: `true`)
+- `limit` - maximum request body size. (default: `<100kb>`)
+- `type` - request content-type to parse (default: `text/plain`)
+- `verify` - function to verify body content
+
+The `type` argument is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) library. This can be an extension name (like `txt`), a mime type (like `text/plain`), or a mime time with a wildcard (like `text/*`).
+
+The `verify` argument, if supplied, is called as `verify(req, res, buf, encoding)`, where `buf` is a `Buffer` of the raw request body and `encoding` is the encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.urlencoded(options)
+
+Returns middleware that only parses `urlencoded` bodies. This parser accepts only UTF-8 encoding of the body and supports automatic inflation of `gzip` and `deflate` encodings.
+
+The options are:
+
+- `extended` - parse extended syntax with the [qs](https://www.npmjs.org/package/qs#readme) module. (default: `true`, but using the default has been deprecated. Please research into the difference between `qs` and `querystring` and choose the appropriate setting)
+- `inflate` - if deflated bodies will be inflated. (default: `true`)
+- `limit` - maximum request body size. (default: `<100kb>`)
+- `parameterLimit` - maximum number of parameters. (default: `1000`)
+- `type` - request content-type to parse (default: `urlencoded`)
+- `verify` - function to verify body content
+
+The `extended` argument allows to choose between parsing the urlencoded data with the `querystring` library (when `false`) or the `qs` library (when `true`). The "extended" syntax allows for rich objects and arrays to be encoded into the urlencoded format, allowing for a JSON-like experience with urlencoded. For more information, please [see the qs library](https://www.npmjs.org/package/qs#readme).
+
+The `parameterLimit` argument controls the maximum number of parameters that are allowed in the urlencoded data. If a request contains more parameters than this value, a 413 will be returned to the client.
+
+The `type` argument is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme) library. This can be an extension name (like `urlencoded`), a mime type (like `application/x-www-form-urlencoded`), or a mime time with a wildcard (like `*/x-www-form-urlencoded`).
+
+The `verify` argument, if supplied, is called as `verify(req, res, buf, encoding)`, where `buf` is a `Buffer` of the raw request body and `encoding` is the encoding of the request. The parsing can be aborted by throwing an error.
+
+### req.body
+
+A new `body` object containing the parsed data is populated on the `request` object after the middleware.
+
+## Examples
+
+### express/connect top-level generic
+
+This example demonstrates adding a generic JSON and urlencoded parser as a top-level middleware, which will parse the bodies of all incoming requests. This is the simplest setup.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse application/x-www-form-urlencoded
+app.use(bodyParser.urlencoded({ extended: false }))
+
+// parse application/json
+app.use(bodyParser.json())
+
+app.use(function (req, res) {
+ res.setHeader('Content-Type', 'text/plain')
+ res.write('you posted:\n')
+ res.end(JSON.stringify(req.body, null, 2))
+})
+```
+
+### express route-specific
+
+This example demonstrates adding body parsers specifically to the routes that need them. In general, this is the most recommend way to use body-parser with express.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// create application/json parser
+var jsonParser = bodyParser.json()
+
+// create application/x-www-form-urlencoded parser
+var urlencodedParser = bodyParser.urlencoded({ extended: false })
+
+// POST /login gets urlencoded bodies
+app.post('/login', urlencodedParser, function (req, res) {
+ if (!req.body) return res.sendStatus(400)
+ res.send('welcome, ' + req.body.username)
+})
+
+// POST /api/users gets JSON bodies
+app.post('/api/users', jsonParser, function (req, res) {
+ if (!req.body) return res.sendStatus(400)
+ // create user in req.body
+})
+```
+
+### change content-type for parsers
+
+All the parsers accept a `type` option which allows you to change the `Content-Type` that the middleware will parse.
+
+```js
+// parse various different custom JSON types as JSON
+app.use(bodyParser.json({ type: 'application/*+json' }))
+
+// parse some custom thing into a Buffer
+app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
+
+// parse an HTML body into a string
+app.use(bodyParser.text({ type: 'text/html' }))
+```
